N2 - The kinetics of the thermal decomposition of acetylacetone has been studied in a shock tube in the temperature range of 1120–1660 K. Detailed analyses of CO and H2O formation data indicate that H2O is formed by a four‐center molecular channel, whereas CO is formed by the rapid dissociation of CH3CO produced by the CC bond dissociation of acetylacetone. The Arrhenius equations for H2O and CH3CO formation channels are 퓀2 = 1014.24±0.21 exp(−60,800 ± 1,220/RT)sec−1 and 퓀3 = 1017.05±0.28 exp(−74,600 ± 1,680/RT) sec−1, respectively. The results of the study suggest that the six‐center molecular channel for the production of acetone and ketene is not important under the condition used in this investigation.
